This is a good perspective; I hadn't thought about it that way.
I'm surprised the studios are dragging their heels so much; this is the future of media. Why aren't they on board?
Look at it from Starz' perspective. They're not dragging their heels, they're trying to protect their very business from going under.
Netflix offered them like $700million (around there someplace, iirc), to be able to stream their content. Sounds great!
Except if you're Starz. Once Netflix is streaming their content, people no longer need to subscribe to Starz the channel. If people don't subscribe to the channel, there goes their main source of revenue and a large part of what's keeping them afloat in general.
If they lose subscribers to Netflix streaming, they lose the revenue that allows them to license movies and to create programming. Hence Netflix no longer wants to pay those astronomical licensing amounts - and Netflix can try to cut deals with the studios themselves, and cut Starz' out as the middleman.
Then Starz would cease to exist - if Netflix goes around them (and says to the studios, who need the cash to make the movies, 'we paid Starz $700 mil and Showtime $700 mil to license the movies they licensed from you, how bout we just pay you $1.5 billion for the direct licenses?') they lose subscribers who now have no reason to use their services.
Starz is trying to keep themselves relevant and afloat. If the other channels went Starz' way, Netflix will have a hard time increasing streaming content or getting relevant streaming content, unless they try to make the end run anyway. Starz has an argument to make with the studios, as to why the studios shouldn't cut them out and license with Netflix directly, as long as they keep their subscribers.
